1 Overview of Public Health Surveillance Denise Koo, MD, MPH Epidemiology Program Office Centers for Disease Control and Prevention

2 Public Health Approach ProblemResponse Surveillance: What is the problem? Risk Factor Identification: What is the cause? Intervention Evaluation: What works? Implementation: How do you do it?

3 Public Health Surveillance Ongoing, systematic collection, analysis, and interpretation of health-related data essential to the planning, implementation, and evaluation of public health practice, closely integrated with the timely dissemination of these data to those responsible for prevention and control.

4 Public Health Surveillance Systematic, ongoing Collection Analysis Interpretation Dissemination Link to public health practice

5 Purposes of Public Health Surveillance Assess public health status Define public health priorities Evaluate programs Stimulate research

6 Core Public Health Functions Assessment Policy development Assurance

7 Surveillance Information for Action

8 Uses of Public Health Surveillance Estimate magnitude of the problem Determine geographic distribution of illness Portray the natural history of a disease Detect epidemics/define a problem Generate hypotheses, stimulate research Evaluate control measures Monitor changes in infectious agents Detect changes in health practices Facilitate planning

9 Uses of Public Health Surveillance Estimate magnitude of the problem Determine geographic distribution of illness Portray the natural history of a disease Detect epidemics/define a problem Generate hypotheses, stimulate research Evaluate control measures Monitor changes in infectious agents Detect changes in health practices Facilitate planning
